A safe, native-sized Forth.

Ferth is a [Forth-2012 standard system](https://forth-standard.org/standard/label).

This project provides both the `ferth` crate and the `ferth` command-line interpreter.

## Highlights

* Zero-dependency, `no_std` core

* Safe by default

* Native cell width (32- or 64-bit integers)

* Configurable memory and stack sizes

* Tail-call optimization

## Install

Download a pre-built binary of the [latest release](https://github.com/benwebber/ferth/releases/latest) for your system.

Or install with Cargo:

```

cargo install ferth --features repl

```

## Usage

ferth [-m MEMORY] [-d STACK_CELLS] [-r RETURN_STACK_CELLS] [FILE]
